Abstract

Provided herein are modified NK-92® cells comprising one or more nucleic acids encoding i) a homing receptor, ii) Antigen Binding Protein (ABP) or Chimeric Antigen Receptor (CAR) that specifically binds to a target antigen, iii) an Fc Receptor such as CD16 or CD16-158V, and/or iv) a cytokine, wherein the nucleic acid sequence is operably linked to a promoter. Further provided herein are modified NK-92® cells comprising one or more nucleic acids encoding i) IL-12 and/or TGF-beta trap, ii) an Antigen Binding Protein (ABP) or Chimeric Antigen Receptor (CAR) that specifically binds to a target antigen, iii) an Fc Receptor such as CD16 or CD16-158V, and/or iv) a cytokine, wherein the nucleic acid sequence is operably linked to a promoter. Also provided are compositions and kits comprising the modified NK-92® cells, as well as methods of treating cancer using the modified cells.

Claims (11)

1. A method of treating a cancer or reducing cancer metastasis in a subject, the method comprising:

administering to the subject a therapeutically effective amount of natural killer-92 (NK-92) cells transfected with a recombinant quadricistronic nucleic acid, wherein the NK-92 cells have American Type Culture Collection (ATCC) deposit number CRL-2407,

wherein the recombinant quadricistronic nucleic acid includes a sequence encoding a cluster of differentiation 19-chimeric antigen receptor (CD19-CAR), a C—C chemokine receptor type 7 (CCR7), a cluster of differentiation 19 (CD16) 158V variant having an amino acid sequence of SEQ ID NO:12, and an endoplasmic reticulum directed Interleukin-2 (erIL-2), and expresses CD19-CAR, the CCR7, the CD16 158V variant, and the erIL-2, wherein the sequence encoding the CD19 CAR comprises the nucleotide sequence of SEQ ID NO:25,

wherein surface expression of the CCR7 enables the recombinant NK-92 cell to migrate towards CCL21 and/or CCL19; and

wherein administration treats the cancer, or reduces cancer metastasis in the subject.

2. The method of claim 1 , wherein from 1×10 3 to 1×10 10 , per m 2 of the recombinant NK-92 cells are administered to the subject.

3. The method of claim 1 , wherein the recombinant NK-92 cells are administered parenterally, intravenously, peritumorally, intratumorally, or by infusion.

4. The method of claim 1 , wherein the nucleic acid encoding the CCR7 has a nucleic acid of SEQ ID NO:1 or a nucleic acid of SEQ ID NO:22 or a nucleic acid that encodes the polypeptide of SEQ ID NO:44.

5. The method of claim 1 , wherein the nucleic acid encoding the CD16 158V variant has a nucleic acid of SEQ ID NO:26.

6. The method of claim 1 , wherein the nucleic acid encoding the erIL-2 has a nucleic acid of SEQ ID NO:14 or a nucleic acid that encodes the polypeptide of SEQ ID NO:15.

7. The method of claim 1 , wherein the nucleic acid encoding the CCR7 has a nucleic acid of SEQ ID NO:1 or a nucleic acid of SEQ ID NO:22 or a nucleic acid that encodes the polypeptide of SEQ ID NO:44, wherein the nucleic acid encoding the CD16 158V variant has a nucleic acid of SEQ ID NO:26, and wherein the nucleic acid encoding the erIL-2 has a nucleic acid of SEQ ID NO:14 or a nucleic acid that encodes the polypeptide of SEQ ID NO:15.
